T allwhom it may concern:

Be it known that I, EDWARD C. CORADO, of the city of Winnipeg, Provinceof Manitoba, Dominion of Canada, a subject of the King of Great Britain,have invented" certain new and useful. Improvements in HydrocarbonBurners; and I do hereby declare that the following is a full, clear,and ex- Further objects of my invention are to' provide a simple andcompact burner in which better combustion will be obtained, and in whichthe accumulation of gases in the base thereof with consequentoverheating will be prevented. I

To this end my invention consists of the particular construction andarrangement of parts hereinafter described and pointed out in theclaims.

For full comprehension, however, of my invention reference must be hadto the accompanying drawings in which similar reference charactersindicate the same parts, and wherein:

Figure 1 is a side elevation partly in section of a burner constructedaccording to my invention;

Figure 2 is a horizontal sectional view taken on line 22 Figure 1;

Figure 3 is a vertical sectional view taken on line 3-3 Figure 2;

F igure4is a vertical sectional view taken on line 44 Figure 2;

Figure 5 is a detail elevation of the burner cap removed; a Figure 6 isa view similar to Figure 2 and illustrating a modification of myinvention; and I Figure 7 is a detail fragmentary sectional view of thetelescoped portion of the wick shaft.

A burner illustrating the preferred embodiment of my invention is shownin the accompanying drawings and consists of a body constituted by abase portion and a cap detachably mounted thereon, a combined means forfeeding the wick and for snuffing the same, and a detachable chimneysupporting bracket.

The base contains a chamber 4 which is enclosed by a surrounding sidewall 5, bottom 6, and top 7, the lower end of the base being reduced andscrew-threaded as at 8 for connection to the oil font a portion of whichis indicated at 9. The wick tube 10 is of rectangular cross-section and[extends from a central opening in the bottom to a short distance abovethe top.

In order to prevent the accumulation of gases within the chamber 4 andthe font with consequent overheating the bottom is provided withopenings 12 and the side wall with a circumferential series of openings13 communncation being thereby effected between the interior of the fontand the atmosphere.

The burner cap is indicated at 15 and consists of a member ofsubstantially hemispherical form the rim of which is curved in the formof a bead as indicated at 16. It is provided with the usual flame exitslot 17. To detachably fasten the cap upon the base, the top of thelatter is circumferentially flanged as at 18 with upturned lips 19'and20 curved to receive the bead 16, the flange being extended laterally asat 21 at a point diametrically opposite these lips and provided with aslot 22. This slot accommodates the free end of a springclip 23 ofU-form riveted to the under side of the extension as at 24 andconstructed and arranged to'engage the bead 16 on the cap, the extremeend of the clip being bent out at an angle as at 25 to provide athumb-hold when releasing the cap.

The wick feeding means consists of the usual sprocket wheel mounted upona shaft 31 fixed against axial movement and extending across the chamber4 and journalled in the side wall 5 thereof. This wick feedin means mayor may not be combined with t e snufling mechamsm, as illustrated inFigures 1 and 6. I find it preferable to employ the wick-feedin shaft 31as a means for operatin the snu er to be hereinafter described an tothis end the operating end by the burner base.

1 opening 46'.

of the shaft is provided with a telescope extension 32 the outer end ofwhich has the usual finger hold 33. V 7

Approximately half the length of this section is of sleeve form asindicated at '84 the sleeve enclosing the outer end of the shaft: 31 andrelative displacement therebetween being prevented by a pin 35 on thelatter moving in a slot 36 in the former.

The snuffer proper is mounted within the burner cap '15 and detachabletherewith while the means for actuating it is carried The'snufler properconsists of a member v40 of inverted cup form similar to that of theburner cap. This member is more than a snufier as it assists inmaintaining the equilibrium of the shaft. I will therefore refer to thismember as the inside cap, the burnereap, as hereinbefore stat-ed, beingthe outside cap. This inside cap is fulcrurned :within the same upontrunnions .41 journalled'in openings 42, the trunnions being constitutedby the outwardly bent ends of a wire 43 of U-form' fitted withinv theinside cap with the ends projecting through open ings therein. A lip 44secures the wire at its middle to the cap.

The inside capis provided with anelongated opening or slot 45 invertical align- Yment with the flame opening in the outside cap andbridged by a snuffing strip 46 coustructed and arranged to directly actupon the top of the wick, the portion of the opening normally locatedbeneath the opening in the cap constituting a flame opening the top ofthe burner base and moving in" guides 51 formed integrally therewith andI through notches 90 in the bead '16 of the burner cap. This rod carriesa forked device 52 between the arms'of'which a lever 53 on the capprojects, the arms being constructed and arranged to engage the leverand cause the inside cap to oscillate when a thrust is exerted upon thepush-rod.

The latter is operatively connected to the telescopic section of thewick feeding shaft by an oblong disc 60 mounted upon the end of thepush-rod and encircling the telescopic section between collars 61 butpermitting the" movable axially relatively to the shaft rotation of thesame.

between a pin 62 A helicalspring 62 encircles the shaft 31 f proj ectingtherethrough and a seat 63 at the mouth of the sleeve which is ofincreased diameter. This spring yieldingly maintains the inside cap inposition with the flame opening 45 in vertical alignment with the flameopening in the cap.

The latter is provided with four air inlet openings of semicircular formlocated two on each side of the vertical axial flame of the trunnions 41and adjacent the bead 16, and an opening 71 on each side of the flameopening and above the first mentioned open in s.

ln snufling the wick of a lamp in use, the lamp tender. has but topushinwardly on the telescopic section 32, the outer end of which is'locatedoutside the lamps. This action, through push-rod 50, fork 52 and lever53, oscillates the inside cap on its trunnions thereby moving'the,snuiiing strip 46 across thetop of thewickn As the telescopic section isrelieved of pressure the spring 62 causesit to "return to itsinitial'position moving the push-rod and snuifer withit. This operationmay be repeated as often as it is required to remove the carbonaccumulation on the wick. Rotation of the wick shaft does not affect theinside cap in anyway.

With my improved construction and arrangement of parts the lamp tenderis able to take full advantage of the capacity of the oil fontwhich inrailway switch lamps is suflicient to last four or five days in that hedoesnot have to open up the lamp until the font needs filling.

In the modification illustrated in Figure '6 the push-rod 50 is notconnected to the telescopic section of the wick-shaft and the spring 62is transferred from the latter to the push-rod.
